It measures 41.2 × 80 mm and has 4 copper layers, 1.6 mm thick.
What parts does the XIAO ePaper Display Board EE03 V1.0 use?
359 parts, built around the SHT40-AD1B-R2, TPS22916CYFPR, BQ24070RHLR and ETA3410D2I-T. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the XIAO ePaper Display Board EE03 V1.0 KiCad files?
From the Herasium/e-ink repository on GitHub, at the commit this page was made from: the board is IT8951/XIAO ePaper Display Board EE03_V1.0_SCH & PCB_251217/XIAO ePaper Display Board EE03_V1.0.kicad_pcb and its schematic IT8951/XIAO ePaper Display Board EE03_V1.0_SCH & PCB_251217/01 Descriptions.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the XIAO ePaper Display Board EE03 V1.0 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Herasium before reusing the design.
